,v Request for Relief 04-CN-002 Page 2 of 6 IV. Basis for Relief Paragraph A: During the ultrasonic examination of the Seal Water Injection Filter 2A Shell-to-Head Circumferential Weld, 100% coverage of the required examination volume could not be obtained (See Attachment A-I). ASME, Section XI, Appendix III, III4420 requires scanning of the examination volume from two beam path directions. This requirement could not be complied with because of a sharp transition in thickness from the head to the shell. The examination coverage was limited to 50.94 %. The percentage of coverage reported represents the aggregate coverage of all scans performed on the weld. 62% (head side) of the required volume was examined in one axial direction, 27% (shell side) was examined in the other axial direction and 57% of the required volume was examined in two circumferential directions. In addition, austenitic weld metal characteristics prevent using the second sound path leg to obtain coverage. In order to achieve more coverage, the weld would have to be re-designed to allow scanning from both sides of the weld, which is impractical. The percentage of coverage reported represents the aggregate coverage of all scans performed on the weld. (Examination Data for Weld ID. Number 2ASWINJF-SH-HD is shown in Attachment A) (High Pressure Filter Assembly - Attachment A-I) Paragraph B: During the ultrasonic examination of the NI System Elbow-to Tee Circumferential Weld 2N172-2, coverage of the required examination volume could not be achieved from two axial and two circumferential directions. Duke Energy Corporation does not take credit for examining the far side on austenitic piping welds where the sound beam must penetrate the weld metal and access is restricted to one side of the weld. The examination coverage was limited to 75%. Because of the outside diameter taper on the tee side of the weld scanning in the axial direction from that side was not performed. In addition, austenitic weld metal characteristics prevent using the second sound path leg to obtain coverage. The percentage of coverage reported represents the aggregate coverage of all scans performed on the weld. 100% of the examination volume was covered in one axial direction and two circumferential directions. (Examination Data for Weld ID. Number ID. 2N172-2 is shown in Attachment B) Paragraph C: During the ultrasonic examination of the NI System Tee-to-Reducer Circumferential Weld 2N172-3, coverage of the required examination volume could not be achieved from two axial and two circumferential directions. Duke Energy Corporation does not take credit for examining the far side on austenitic piping welds where the sound beam must penetrate the weld metal and access is restricted to one side of the weld. The examination coverage was limited to 75%. Because of the outside diameter taper on the tee side of the weld scanning in the axial direction from that side was not performed. In addition, austenitic weld metal characteristics prevent using the second sound path leg to obtain coverage. The percentage of coverage reported represents the aggregate coverage of all scans performed on the weld. 100% of the examination volume was covered in one axial direction and two circumferential directions. In order to achieve more coverage, the weld would have to be re-designed to allow scanning from both sides of the weld, which is impractical. (Examination Data for Weld ID. Number ID. 2N172-3 is shown in Attachment C) Paragraph D: During the ultrasonic examination of the NI System Tee-to-Pipe Circumferential Weld 2N188-3, coverage of the required examination volume could not be achieved from two axial and two circumferential directions.

In order to achieve more coverage, the weld would have to be re-designed to allow scanning from both sides of the weld, which is impractical. (Examination Data for Weld ID. Number ID. 2N188-3 is shown in Attachment D) Paragraph E: During the ultrasonic examination of the CF System Valve 2CF168-to-Elbow'Circumferential Weld 2CF100-60, coverage of the required examination volume could not be achieved from two axial and two circumferential directions. Duke Energy Corporation does not take credit for examining the far side on austenitic piping welds where the sound beam must penetrate the weld metal and access is restricted to one side of the weld. The examination coverage was limited to 75%. Because of the outside diameter taper on the valve side of the weld, scanning in the axial direction from that side was not performed. In addition, austenitic weld metal characteristics prevent using the second sound path leg to obtain coverage. The percentage of coverage reported represents the aggregate coverage of all scans performed on the weld. 100% of the examination volume was covered in one axial direction and two circumferential directions. In order to achieve more coverage, the weld would have to be re-designed to allow scanning from both sides of the weld, which is impractical. (Examination Data for Weld ID. Number ID. 2CF100-60 is shown in Attachment E) V. Alternate Examinations or Testing Paragraph F: There are no scheduled alternative examinations or testing. However; Duke Energy proposes to use required future pressure test and VT-2 visual examinations to complement the limited ultrasonic examination coverage. Based on the coverage and results of the required volumetric and surface examinations this outage and the Code required pressure testing (VT-2) examinations, it is Duke's belief that this combination of examinations provides a reasonable assurance of component integrity. VI. Justification for Granting Relief Paragraph G: Ultrasonic examinations were performed using personnel, procedures and equipment qualified in accordance with ASME Section XI, Appendix VIII, 1995 Edition through the 1996 Addenda as administered through the Performance Demonstration Initiative (PDI). Currently PDI does not issue a qualification for single sided examination of austenitic piping welds. However a best effort examination was performed on the weld metal and far side base material using refracted longitudinal waves, which is considered to be the best available technique. The NI system welds that were identified in the relief request (2N192-4, 2N172-3, 2N188-3) are on piping from the ND system to the Hot and Cold Leg injection lines. These pipes are not in an active portion of the system. The pipes are filled with FW (Refueling Water System) system water at a low pressure FWST (Refueling Water Storage Tank) static head. Since this piping is in the Containment Building, if a small leak in the weld were to occur, it is highly likely that the leak would continue for a significant amount of time before being noticed.
Request for Relief 04-CN-002 Page 4 of 6 Since this is low energy FW 3wvater, a leak would be undetectable usinig ihe Containment Atmosphere Gaseous and Particulate Radioactivity Monitoring (EMF monitors 38 and 39). The Containment Ventilation Unit Condensate Drain Tank level would likely not increase since the water leaking through the pipe is low energy and the location of the weld in not in a hot environment. A leak would need to be significant before a decreasing trend is noticed on the FWST level. It is likely that a leak in the identified NI system welds would only be discovered during a refueling outage, beginning with the pre-outage containment walkdown. The water in the pipe is highly borated and would likely leave a significant amount of boron accumulation on the pipe and surrounding area. This boron accumulation would most likely be noticed during the course of a refueling outage. There is also a possibility that a leak would be discovered by monitoring the Containment Floor and Equipment Sump level/inputs. However, since there is always an input to Containment Floor and Equipment Sump A, the leak would not be noticed unless it was significant. Significant leakage through the welds would likely be identified by Containment Floor and Equipment Sump level indication. There would have to be a gross failure of the welds for any significant impact to occur in the Refueling Water Storage Tank (FWST) level. One of these welds, Elbow-to-Pipe Weld #2NI924, received an ultrasonic and a dye penetrant examination during the First Inspection Interval. There were no reportable conditions found. In summary, it is possible for a small leak to develop in welds 2N172-2, 2NI72-3, and 2NI88-3 and remain unnoticed for several months. This is mainly due to the pipe being filled with low energy FW system water. The systems and processes established to detect leaks inside containment mainly focus on pipes containing high energy water or water with high amounts of radiological activity. However, with 75% scanning coverage for Weld ID's 2NI72-2, 2NI72-3 and 2NI88-3 obtained, and with the fact no indications were found during the surface examinations on these welds, reasonable assurance of weld integrity is provided. Paragraph H: Ultrasonic examinations were performed in accordance with ASME Section XI, Appendix III. The examination performed on the weld metal and far side base material used refracted longitudinal waves, which is considered to be the best available technique. Seal Water Injection Filter 2A Shell-to-Head Circumferential Weld 2ASWINJF-SH-HD is located outside containment. If a leak were to develop at this weld location, the instrumentation available to the operators for detection and monitoring of leakage would provide prompt and qualitative information necessary to permit them to take immediate corrective action. If a leak should develop in this aforementioned location, the corrective action would be to isolate the leak and place the other seal water injection filter in service. This corrective action is governed by approved procedures. Additionally, other indicators are also available to the operator that a leak exists: Charging / Letdown system mismatches. Inspection for leakage around the "filter casing head" whenever the filters are changed. Procedure OP/l/A/6200/001, Chemical and Volume Control System, has a step to "verify no leakage from around the filter casing head". U
Request for Relief 04-CN-002 Page 5 of 6 Paragraph I: Ultrasonic examinations were performed using personnel, procedures and equipment qualified in accordance with ASME Section XI, Appendix VIII, 1995 Edition through the 1996 Addenda as administered through the Performance Demonstration Initiative (PDI). Currently PDI does not issue a qualification for single sided examination of austenitic piping welds. However, a best effort examination was performed on the weld metal and far side base material using refracted longitudinal waves, which is considered to be the best available technique. The CF system weld identified in the relief request is on Unit 2 feedwater piping that maintains a constant tempering flow to the auxiliary feedwater nozzle on the "C" Steam Generator. Fluid within the piping is at steam generator feedwater temperature and pressure conditions during normal operations. The piping is rated Class B. The piping is routed through a floor penetration on the 594' elevation of the Unit 2 Interior Doghouse. The subject weld is located several feet from the handrail for the observation platform for this elevation. The weld area is at eye level and a direct line of sight to the weld area is maintained along normal travel paths on this platform. The operations staff conducts weekly inspections of the Interior Doghouse with specific instructions to identify steam or secondary side water leaks. If a leak were to develop at the weld location discussed in the relief request, some of the high temperature fluid would immediately flash to steam. Blanket insulation is installed on the piping downstream of the weld area. However, there is a gap in the insulation coverage in the area of the weld at the transition from valve 2CF168 to the downstream piping. This insulation configuration ensures that weld leakage would be readily apparent to personnel traveling through the area. In addition to the periodic room inspections, safety-grade level switches are installed on the foundation floors of the Doghouse rooms. These switches are designed to protect safety-related components in the room from a pipe leak and subsequent room flooding. A safety-related feedwater isolation signal for the "B" and "C" Steam Generators would be generated if leakage from the weld accumulated on the floor below the weld area. If a leak were discovered, a work request would be written and the leak would be evaluated under the Fluid Leak Management process. Since the piping is rated Class B, the criteria of Selected Licensee Commitments (SLC) 16.5-5 "Structural Integrity" would be applicable. Weld repairs would require a unit downpower as the weld area can not be isolated from the main feedwater piping.
Request for Relief 04-CN-002 Page 6 of 6 VII. Implementation Schedule Paragraph J: The scheduled second 10-year interval plan code examination was performed on the referenced welds resulting in limited volumetric coverage. No additional examinations are planned for the welds during the current inspection interval. The same welds may be examined again as part of the next (third) 10-year interval plan, depending on the applicable code year edition and addenda requirements adopted in the future. VIII.
